Many studies report on the association between 2D:4D, a putative marker for prenatal testosterone exposure, and economic preferences. However, most of these studies have limited sample sizes and test multiple hypotheses (without preregistration). In this study we mainly replicate the common specifications found in the literature for the association between the 2D:4D ratio and risk taking, the willingness to compete, and dictator game giving separately. In a sample of 330 women we find no robust ...

A growing body of correlational studies suggests that sex hormones such as those contained in, or affected by, oral contraceptives (OCs) may impact economic behavior. However, despite widespread use of OCs among women in Western countries, little is known about their potential behavioral effects. The present study investigates whether OCs causally influence economic preferences. We randomly allocate 340 women aged 18–35 to three months of a widely used OC or placebo treatment. At the end of trea...

AbstractStromal factors have been identified as important for tumorigenesis and metastases of breast cancer. From 49 premenopausal women, samples were collected from benign or malignant tumors and the seemingly normal tissue adjacent to the tumor. The factors studied, with real-time polymerase chain reaction (PCR) and immunohistochemistry, were cyclooxygenase-1 and cyclooxygenase-2 (COX-1 and COX-2), syndecan-1 (S-1) and connective tissue growth factor (CTGF).COX-1 and S-1 mRNA levels were highe...

Context: There is a lack of knowledge about how oral contraceptives may affect sexual function. Objective: To determine whether there is a causal effect of oral contraceptives on sexuality. We hypothesized that a widely used pill impairs sexuality. Design: A double-blind, randomized, placebo-controlled trial. Enrollment began in February 2012 and was completed in August 2015. Setting: Karolinska University Hospital, Stockholm, Sweden. Participants: A total of 340 healthy women, aged 18–35 years,...

AbstractUnintended pregnancy is an important public health problem worldwide. Unwanted pregnancies may end in induced abortion (legal or illegal, safe or unsafe) or in childbirth. In many parts of the world both can be life threatening. Even where both are safe, abortion is distressing for all concerned while unwanted births often lead to poor health and social outcomes for both the mother and her child.
The effectiveness of soy isoflavones to prevent bone loss in postmenopausal women is controversial. While consumption of soy in Vietnam is very high, we recently reported a prevalence of osteoporosis comparable to that of many Western populations. In the present study, we analyzed the isoflavone content of soy drink products commercially available in Vietnam and Sweden, and we also compared these products to ”home-made” soy drink from beans of different origin. The amounts of the bioactive aglyc...

Objective. To analyze the effects of testosterone addition to estrogen therapy in comparison with estrogen alone on cardiovascular risk factors in postmenopausal women.Methods. Fifty surgically postmenopausal women were included in this double-blind, placebo-controlled and randomized study to receive daily oral treatment with estradiol valerate 2 mg + placebo (E/P) or estradiol valerate 2 mg + testosterone undecanoate 40 mg (E/T) for 24 weeks and then switched to the other regimen for another 24...

Summary This cross-sectional study showed that peak bone mineral density in Vietnamese women is comparable to that in Caucasian women; however, the prevalence of osteoporosis in post-menopausal Vietnamese women was slightly higher than in Caucasian women. The age of achieving peak bone mass in Vietnamese women was between 26 and 30 years.
